Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471094, here are decompositions:

3 + 31471091 = 31471094
43 + 31471051 = 31471094
97 + 31470997 = 31471094
103 + 31470991 = 31471094
181 + 31470913 = 31471094
241 + 31470853 = 31471094
271 + 31470823 = 31471094
307 + 31470787 = 31471094

Showing the first eight; more decompositions exist.
